To perform visual print quality assessment various print quality metrics need to be measured and analyzed.

The measurements made will be used by pen architects, writing system engineers, ink chemists and product

quality assessment teams. These measurements are done by an image processing software which performs the

print quality measurements on the image of a diagnostic plot. The diagnostic plot image may be acquired from

various image acquisition systems, example scanners, area scan camera, line scan camera etc. Diagnostic plots

contain predefined patterns designed to measure specific aspects of print quality. In this work, we propose a

method to determine the print scaling error introduced during print process and show extended application of

the determined affine transformation matrix in correcting the inspection ROI (Region of Interest) placement.
